In Plex Web, at least, geotagged photos will show a map when you open the Information panel. Clicking on the map will open a new tab to Google Maps, centered on the location. There is currently a known bug, though, as this is not working for .dng files. It works well for .jpg files.
Not sure if this is possible or practical with a device like Apple TV or Roku. I haven’t seen a good map app.
